Title: Hot water transportation to heat demanding site
Inventor: FUJII YOSHIHISA
IPC: F04F1/18
Filed: 1985-09-26
Abstract: PURPOSE:To transfer hot wafer to the heat demanding location by the so-called air lift effect of lifting up hot water inside a lift pipe by the lifting force of freon bubbles generated when liquid freon is fed from the lower part of a lift pipe into hot water and heated. CONSTITUTION:Hot waste water 11 at 50-80 deg.C is stored inside a hot-water tank 1 and heats water inside a lift pipe 2. When liquid freon F-1 is poured into the lift pipe 2 from a freon supply pipe 4 via a valve V, water is addition ally heated by hot water HW until boilded and expanded to form freon bubbles F-2, which are lifted to the upper area inside the lift pipe 2. At this time, hot water HW is also elevated up into a head tank 3 by the lift effect of bubbles. Hot water HW which is separated from freon in a steam separating drum 31 is then transported efficiently to a heat demanding location through a downcomer 5 and a feed pipe 6. On the other hand, freon bubbles F-2 are cooled by an in air cooling capacitor 32 to change to liquid freon F-1 and the liquid freon is fed back into the freon supply pipe 4. Hot water transportation without any power supply can therefore be attained.

Title: Pilot signal system in code hopping spread spectrum communication system
Inventor: NAGAZUMI YASUO
IPC: H04B1/7073
Filed: 1987-08-27
Abstract: PURPOSE:To surely and quickly obtain synchronization at code hopping by outgoing a level transition pulse train corresponding to the code prior to the start of code modulation by pseudo noise as a pilot signal. CONSTITUTION:At least one shoed noises selected among plural pseudo noise generators 102 and used as a code modulation for an input signal as a spread code at the transmission and the reference code is used to demodulate a reception signal by the synchronization of the reference code of an S unit 18 corresponding individually to the selected noise. In selecting the pseudo noise, prior to the start of code modulation by the normal noise to be selected, a code transition pulse train corresponding to the code is originated as a pilot signal.

Title: Oil feed device
Inventor: TERASAKI MASATOSHI
IPC: F16N7/38
Filed: 1982-12-08
Abstract: PURPOSE:To supply cooling oil to a mechanical shaft seal even upon emergency such as, for example, electrical power failue, to prevent the bearing from seizing, by setting a solenoid valve in its closed condition upon power failure to ensure a necessary pressure between two check valves in order to provide the drop of pilot pressure with a time lag. CONSTITUTION:Two check valves 6, 14 are provided on the primary side of a mechanical shaft seal 2, a relief valve 7 is provided to bypass a solenoid valve 16, and a pressure switch 15 is disposed in the intermediate section of a pipe line 11 connecting between the check valve 6 and the mechanical sahft seal 2. Upon electrical power failure a turbo-machine 1 and an oil pump 4 stop simultaneously. However, since the solenoid valve 16 is also closed at the same time, the pressure in a pipe 13 for actuating an accumulator 8 is always lower than that in a pipe line 17 by a pressure loss. Therefore, a pilot check valve 9 is maintained to be closed until oil in the accumulator 8 is discharged. Oil supply is not interrupted in this time, and therefore the mechanical shaft will never seize during successive rotation of the rotor due to its inertia force.
